class_docstr: Object returned by the HB_master.run function
  
  This class offers a simple API to access the information from
  a Hyperband run.
docstr: Returns the best configurations over time
  
  
  Parameters
  ----------
          all_budgets: bool
                  If set to true all runs (even those not with the largest budget) can be the incumbent.
                  Otherwise, only full budget runs are considered
          bigger_is_better:bool
                  flag whether an evaluation on a larger budget is always considered better.
                  If True, the incumbent might increase for the first evaluations on a bigger budget
          non_decreasing_budget: bool
                  flag whether the budget of a new incumbent should be at least as big as the one for
                  the current incumbent.
  Returns
  -------
          dict:
                  dictionary with all the config IDs, the times the runs
                  finished, their respective budgets, and corresponding losses
